A voltage reducer is recommended when you are installing 12V accessories, such as lights and a stereo, on your 36V or 48V golf cart. We have voltage reducers for E-Z-GO, Club Car, and Yamaha from 10 Amps to 30 Amps. Adding 12V accessories to your golf cart and running them off one or two of your batteries can lead to an imbalance in your golf cart's battery pack and may shorten the life of your batteries. Using one of our voltage reducers will eliminate this problem.
